I haven't heard of any socketed studs on a bike tire, or car tire. Is there such a thing on a car tire? I'd imagine there would be a large weight penalty for sockets plus studs on a bike tire. I know you can certainly remove studs on a bike tire and replace them. Removing them, then riding, then re-installing would require thoroughly cleaning out each stud seat in the tire before re-installing the stud. I ride studs in the winter here on a regular non-fat MTN bike.
